Blockchain traceability
What it is
Recording each step of a supply chain - farm, procurement, milling, packing, shipment - on a shared ledger that participants cannot retrospectively alter, usually surfaced to the buyer through a QR code on the pack
In agri exports it is used to evidence origin, variety, residue testing and chain of custody for markets with strict import requirements
Impact on industries
- Answers what destination markets are tightening on - origin and residue documentation for EU and US buyers, where a rejected consignment costs far more
- Supports GI and premium claims with verifiable evidence rather than assertion, which is what converts a quality story into realisable price
- Value depends entirely on the accuracy of what is entered at the farm gate - an immutable ledger records unverified data just as faithfully as verified data
- Cost and digital capability sit beyond most aggregators and small mills, so adoption stays thin across the fragmented base
